TAX is not being calculated in one specific country

Hi there!

I have a problem with calculating TAX. Everything works just fine for all countries inside EU, but we also ship to Switserland and somehow TAX is not being calculated when someone from Switserland places an order. The shippingcosts to Switserland are higher and this is being calculated as it should.
Please help! I have no idea where to search...

Kind regards,
Jolanda
